Optical dispensing is a second career for me. I received an honorable discharge after serving as a paratrooper in the United States Army for 13 years. During that time I deployed overseas to Bosnia-Herzegovina, Kuwait and Iraq.

My training in optical dispensing is from the American Career College. There I discovered a passion for excellent quality and customer service. I plan to continue my optical studies and become certified by the American Board of Opticianry.

When not at work I spend time with my wife and two children enjoying outdoor barbeque.

I love working with customers and helping everyone choose their eyeglasses. In particular, I love helping little kids choose their glasses. The look they give you while seeing clearly for the first time through their new prescription eyeglasses is priceless!

I have five years of customer service experience including four years of optical experience in frame and lens selection. I love what I do and look forward to coming to work everyday.
